We design and build custom timber frame horse barns in several styles. Since barns are predominately wood structures, fire prevention is a an absolute necessity in design criteria. Though most everything utilized in a barn is combustible, we work professionally to minimize the flame spread index in the materials that we use. We would offer the following thoughts for fire prevention criteria. 1. Use woods that are a Class B FSI (Flame Spread Index) for structural components and stall partitions. That is below 75 FSI, which would include the following: Spruce (Eastern or Northern white) has a 65 FSI; Douglas Fir (70 FSI), Pacific Silver Fir 69 FSI; Hemlock 60 FSI, but is allergenic to some folks, but is insect resistant as well; Oak is a low Class C in lumber dimensions, but is actually a Class B in heavy timbers, and is recommended for flooring in lofts. 2. Do not use any poplar woods for they are a high Class C at 170-185 FSI. 3. Treated yellow pine is better than untreated pine for stalls and doors. 4. Avoid hollow cavity partitions in constructing stalls and feed rooms, for this creates fire chases that expedite a fire into the loft or ceiling area. Design single solid stall partitions that are strong, and preferably a Class B FSI. 5. If using metal bars for stalls, use EMC Electrical conduit instead of solid steel, to avoid the conductivity of solid, ungrounded steel during a lightning strike. 6. Install all electrical wiring in EMC conduit, with all lighting and receptacles weather tight. 7. Use Ground Fault protection on all receptacles. Please feel free to contact us with questions.
